It includes all the quadrium features such as animation, tweening, mutations, breeding, rendering and sharing, but built around an "iterated fractal system" engine (with both affine and non-affine transformations, including strange attractors)

flame is up to "a not quite release candidate" (it's still missing the online help, but does include 120+ pages of PDF help, but otherwise has only a few minor outstanding bugs). It's got some really cool features, and hopefully will be out in the next couple of weeks...
